I'm an Earl Grey girl or I also love it with cardamom pods in it.
If you haven't tried it you have to. Just get whole pods (a small bag because they lose their aroma quickly) and chuck one or two in your cup or a few more in the tea pot. It doesn't overwhelm the taste just makes it extra yummy.
One of my friends chucks a bit of cinnamon bark in her tea but I don't like it as much as the cardamom.
DH likes the white tea and he's also into herbal ones. We have about 15 differant tea and he picks depending on his mood.
As far as I know the jasmine tea is made by putting the flowers on the tea leaves as they're curing to infuse them with the scent.
